' SPECIFICATION formingpart of Letters Patent No. 724,166, dated March 31 1903.

Application filed June 24,1902. Serial No. 112,948. (No model.)

To all whom, it may concern:

Be it known that I, JOSEPH O. DECKERT, a citizen of the United States, residing in the cityand county ofPhiladelphia,StateofPennsylvania, have invented a new and useful Improvement in Binder-Frames,of which the following is a specification.

My 1nvention relates to a novel construction of a binder-frame which is simple and durable in construction and capable of being readily adjusted to permit of conveniently and quickly binding the leaves insuch a manner that they are readily and separately removable and interchangeable, provision being made for enabling the jaws which retain the leaves in position to be operated simultaneously in a positive and direct manner,

whereby the number of parts are reduced to.

forth, and particularly pointed. out in the claims.

m Figure 1 represents a plan view of abinderframe embodying my invention. Fig. 2 represents a transverse section on line 00 m, Fig. 1. Fig. 3 represents a transverse section on line y, Fig. 1. Fig.4 represents a transverse section on line as, Fig. 1; Fig. 5 rep resents a transverse section on line on w, Fig. 2. Fig. 6 represents a transverse section on line y y, Fig. 3. 'Fig. 7 represents a sectional view, partly in elevation, showing the manner in which the threaded rod is actuated. Fig. 8 represents a plan view of a traveler or traveling arm and its adjuncts slightly dififering from the corresponding device seen in Fig. 1. Figs. 9 and 10 represent sectional views showing different means for forming grooves in the jaws of the binder-frame. Fig. 11 represents a plan view of a modified construction of a binder-frame. Fig. 12 represents a transverse section on line at? 00 Fig. 11. Fig. 13 represents a section on line 2 z, Fig. 12. Fig. 14 represents a sectional view, partly'in side elevation, somewhat similar .to Fig. 12. Fig. 15 represents aperspective view of a-portion of a traveling arm seen in Fig. 11 in detachedposition.

Similar numerals of reference indicate corresponding parts in the figures.

Referring to the drawings, 1 designates a binder-frame, thesame consisting of a back which supports the operative parts of the binder-frame. This back is composed of the back proper or outer portion 2, which is preferably concave in its contour, and the end pieces 3 and 4, rigid with relation to said back proper or outer portion 2. Thus the end pieces are a part of the back, and upon said back, or specifically in said end pieces in the present instance, is rotatably mounted the threaded rod 5, which carries the traveling arm or traveler 6, the latter being curved to conform substantially to the contour of the back 2 and having thereon the lugs or projections 7, which are adapted to engage the walls of the slots 8, which latter are inclined to the axis of the rod 5, as will be understood from Figs. 1 and 5, said slots being located in the curved or arc-shaped jaws 9, which are provided with the wings or end pieces 10, which are pivotally secured at the points 11 to a suitable support-namely, the back, or,

specifically, the end pieces 2 and 3, forming a part of said backsaid arm having the recessed portions 7 theshoulders 8 thereof serving as steps or abutments to limit the downward movement of said jaws.

The leaves that are used in connection with I ICO to remove or insert leaves-the other leaves are held in place by means of these supports.

13 designates a suitable key which is adapted to detachably engage the rod'5, as will be understood from Fig. 7, whereby said rod can be readily rotated according to requirements.

In Fig. 8 I have shown the rod 5 as being provided with arms or travelers 15, which are made in sectionsinstead of one piece,as shown in Fig. 1, as will be understood from said Fig. 8, and provided with the lugs 16, which are adapted to engage slots in the jaws 9 and have the same function as the lugs 7, already described.

In Fig. 9 I have shown the inclined or cam groove corresponding to the groove 8 as being formed between the pairof inclined strips, as 14, whereby a track or guideway 14? is formed.

The operation will be apparent to those skilled in the art. The leaves (not shown) are held in position by means of the contact of the outer portions or edges of the jaws 9 therewith,although itis understood that when the jaws are openthat is to say, arenot clamped upon the leavesthe latter are held loosely in the frame by means of the supports 12. The said jaws are moved toward or away from the leaves by the rotation of the threaded rod 5, it being apparent from Fig. 1 that the rotation of said rod will impart a longitudinal movement to the traveler or traveling arm 6 orarms l5 (seen in Fig. 8) and that the longitudinal movement of said traveler will by reason of the coaction of the lugs or projections 7 with the contiguous cam slot or slots cause said jaws to open and close, as will be understood from Fig. 1.

It will be apparent from the foregoing that the jaws 9 will move simultaneously and in unison and that a positive and direct pressure will be given by said jaws throughout their entire length.

It will be understood by those skilled in the art that if it should be desired to remove a leaf or leaves (not shown) from the jaws the same can be readily done upon turning the threaded rod 5 in the desired direction,which can be readily effected by the application of the key 13 thereto or by other suitable means, whereby said jaws will be moved inwardly, or, in other words, from the position seen in dotted lines in Fig. 4 to the position seen in Figs. 2 and 3, whereby the tension of said leaves will be removed and the desired leaf or leaves can be readily withdrawn, although it is understood that the other leaves are held within the binder-frame when the tension of jaws is removed by the supports 12, after which by rotating the threaded rod in the opposite direction the parts will assume the position seen in dotted lines in Fig. 4 once more.

It will be seen from the foregoing that by my employment of the traveler and the interlocking coacting devices common thereto and to the jaws I am enabled to dispense with toggle'levers, telescoping pins, springs, and

the like, whereby the construction is very reduced to a minimum.

It will be apparent that equivalent devices may be employed in place of the precise structure seen in Figs. 1 to 7, inclusive, since, for example, I may form the cam-groove 14* between the inclined strips 14, as seen in Fig. 9, instead of cutting the same directly in the jaws 9. The traveler or traveling arm 6 may be constructed in two parts, as seen in Fig. 8, which latter is an equivalent construction to that seen in Fig. 2, and other equivalent devices may also be developed by those skilled in this art which come within the scope of this invention.

In Figs. 11 to 15 I have shown anotherembodiment of my invention, wherein the jaws 17 are provided with the inclined ridges 18, which are engaged by suitable ways or recesses 19 on the traveling arm or arms 20, which are mounted upon threaded portions of the rod 21 and movedin unison therewith, as has already been explained, the rotation of the threaded rod 21 serving to actuate said traveling arms or travelers 20 in the desired direction, whereby the opening and closing of the jaws is effected.

In the construction seen in Figs. 12 and 14 I support upon the rods 21 or other suitable portions of the casing or backas, for instance, at the endsthe box or trough-shaped structure 22, which extends transversely or laterally substantially across the open front side of the back and forms a cover for the mechanism within the casing formed by the back, the jaws operating or passing through the spaces between the sides of the box and the back. The pins 24, forming the supports for the leaves in this construction,are secured to the sides 23 of the box 22.

It will be apparent that the trough or pan 22 can be readily removed from the binderframe and that the same serves to conceal the operating mechanism therein.

It is further noted that between the sides of the box or trough-shaped structure 22 and the adjacent portions of the casing forming the back are spaces through which the jaws move in opening and closing, and it will be understood, further, that it is not necessary that the member 22 be made in the form ofa box or trough, since, its function being to cover and conceal the operative parts of a device and to form a back support for the leaves, it could therefore be made in the form of a plate merely and secured at its ends to the end pieces of the casing.

I desire to call special attention to the fact that since the jaws 9 and 17, as well, are each IIO hinged or pivotally supported at theirexbetween said leaves will be much more effectively held in position than would be the case if the jaws moved toward and away from said leaves in a rectilinear line.

In a contemporaneously-pending application filed by me December 5, 1901, hearing Serial No. 84,748, I have shown, described, and broadly claimed mechanism for moving the jaws ofa binder-frame in a circular path, and to the above-described mechanism I herein make no claim.

It will be apparent that various changes may be made in the art which may come within the scope of my invention, and I do not therefore desire to be limited in every instance to the exact construction as herein shown and described.
